Damn he's stupid!

I classify Rush as a cynical manipulator of / panderer to the hyperconservative / fundamentalist base. He is simply pushing buttons. I doubt he even half believes most of his own bullshit; it's quite possible he doesn't believe it at all.

His audience favors arguments from incredulity like this. The BB is inferred based on math and indirect observation. If you're scientifically incurious or illiterate then it is easy for it to not feel "truthy". It doesn't help that the BB was discovered and explained by eggheads, who such people feel insecure around at best, and are disdainful of at worst. It doesn't help that it's a product of science, which fundamentalism actively portrays as unreliable and capriciously "changing its mind" all the time, often using laughably specious arguments to back up this charge, such as that science used to say that the earth is flat, now it says it's spherical (flat earth was in fact a prescientific argument and even at that not as universally accepted as most people think).

Basically, anything to undermine confidence in the scientific method, which has the best possible track record of reliability and improving the human condition of anything we know [sigh].

That is funny. I have been having conversations lately that tend to center at some point on the big bang. While it is true we were not there to see it does not mean we can not ascertain that sequence of events. If you find a window broken and a baseball on the floor in the glass you "know" with out having seen that the ball broke the glass. For the big bang we look at the radio wave signature that we have found and the paterns and movments of the materials in space and we get a very good idea of what happened.

A Physics theory states that it takes an observer to collapse the wave function to determine reality.
He probably read that in a Physics book and put his own spin on it. I don't believe he is intelligent enough to understand Physics.
